9.1.1 Synchronous Calls

Synchronous calls inside the EDT can be achieved by calling the `edt{}` method. This method is smarter than plain `SwingUtilities.invokeAndWait` as it won't throw an exception if called inside the EDT, on the contrary, it will simply call the block of code it was given.

Example:

    class MyController {
        def model    def action1 = {
            // will be invoked inside the EDT by default (pre 0.9.2)
            def value = model.value
            Thread.start {
                // do some calculations
                edt {
                    // back inside the EDT
                    model.result = …
                }
            }
        }    def action2 = {
            // will be invoked outside of the EDT by default (post 0.9.2)
            def value = model.value
            // do some calculations
            edt {
                // back inside the EDT
                model.result = …
            }
        }
    }
